good tour .we were lucky with a sunny day.make sure you take the tour around 10 am because in the afternoon it's crowded due to the rush hour.the explanations are good and you can return to the points of interst you want to visit in more detail. Do not miss Automotive world and a tour of the European Parliament as well as the Church in Sablon.After all Marcolini Chocolatier is right in Sablon.Hop on,hop off is the right Brussels introduction.

The trip to the gardens was great because the guiide from Lindbergh travel gave a nice history of the gardens and about Amsterdam. The gardens are a must see for everyone visiting Amsterdam and the different tulip arrangements are like a fairytale...this year's theme was about Germany so there were quotes from german philosophers and writers next to some arrangements.The timing was excellent.Thank you Viator for making my dream come true

the Holland pass saved for the 2 of us about 120 euros! we used the 3 red tulip tickets (most expensive) foe Amsterdam canal hop on/hop off(22 euros saved pp), Van Gogh museum(14 euros saved pp) and Rijksmuseum (12 euros saved pp). One of the blue (windmill )ticket we used for the one hour canal ride in Amsterdam.Be careful, the canal ride and the canal bus hop on/off are provided by different companies so make sure you consult the guide given with the Holland pass well. 25% savings were at Spido boat in Rotterdam and the Mauritshuis in the Hague.20% savings at Jewish museum and the Portuguese Synagogue in Amsterdam. Worth every penny.
